Fix: [PYTHON] boolean in FormData

[Meldiron]

Currently, if you pass True or Falseinto multiform data, it fails.
This has already been addressed in Node, so I am adding the same fix to Python..

Related issues: appwrite/appwrite#3169

QA code:

from appwrite.client import Client
from appwrite.services.users import Users
from appwrite.services.functions import Functions

client = Client()

(client
  .set_endpoint('https://8080-appwrite-appwrite-....gitpod.io/v1') # Your API Endpoint
  .set_project('...') # Your project ID
  .set_key('...') # Your secret API key
)

func = Functions(client)

result = func.create_deployment('6275052b0a821a3ca033', 'index.py', 'code.tar.gz', True)

print(result)

Results:
